Thanks for checking in @MatanBobi! I've pushed that PR on a prerelease tag while I continue with some smoke testing. Barring any unforeseen problems, I think this should be ready to review for real on Monday. Definitely feel free to take a look in the mean time! |

Companion docs PR to testing-library/svelte-testing-library#375 and svelteness/svelte-jester#283. Svelte 5 introduces the concept of "Svelte modules," which are plain JS and TS files that are run through the Svelte compiler to add support for Svelte 5's "runes" reactivity system.
This is handled well in Vitest by Svelte's first-party
vite-plugin-svelte, but requires additional setup to work in Jest.This PR add newly required Svelte 5 setup instructions for Jest and notes that
svelte-jester >= 5is now required. I'm going to keep this listed as a draft until I've merged and verified testing-library/svelte-testing-library#375 in some real-life projects. That being said, these additionaljest.config.jschanges will not cause any issues with existing Svelte 4 projects
